How to make changes for 100V to 120V
↔
200V to 240V
WARNING :
To prevent personal injuries caused by electric shock hazards or abrupt start of the sewing machine, carry
out the work after turning OFF the power switch and a lapse of 5 minutes or more. To prevent accidents
caused by unaccustomed work or electric shock, request the electric expert or engineer of our dealers when
adjusting the electrical components.
By changing the two points specified below, it is possible to make a
voltage changeover to any of single-phase 100V to 120V, single-
phase 200V to 240V, and 3-phase 200V to 240V.

1) Confirm that the sewing machine is assuredly stopped. Then,
turn off the power supply by means of the POWER switch.
2) Confirm that the POWER switch is OFF and pull off the power
cord from the wall outlet. Since then, wait for at least five minutes.
3) Loosen three screws used to fasten the rear cover of the control
box. Carefully open the rear cover.

actions must be taken carefully.
1) Replacement of the power cord
Change to JUKI authentic part number (M90355800A0) and the
earth cord (M90345800A0).
2) Changeover connector exchange
The voltage changeover connector
is mounted on the FLT
board. Insert this connector in the 100V position.
3) Confirmation of change
Confirm that connection changes have been carried out correctly.
